We supply these Incoloy 800/800H/800HT Stud Bolts in accordance with DIN, ISO, JIS or ANSI Standard.
High-temperature resistance: Incoloy 800 series stud bolts can endure temperatures reaching 1100°C (2000°F) with only minimal reduction in mechanical strength. This makes them well-suited for heat exchangers, petrochemical processing, and other high-temperature settings.
Corrosion Resistance: These alloys demonstrate outstanding corrosion resistance in both oxidizing and reducing areas. They are especially resistant to sulfuric environments, which makes them ideal for use in settings such as pharmaceutical plants.
Creep and Rupture Strength: The blend of nickel, chromium and iron in Incoloy 800 series alloys delivers excellent creep and rupture strength at elevated temperatures. This maintains the stud bolts’ system integrity even when subjected to the heat of growing mechanical stresses over time.
Excellent mechanical strength: The stud bolts of the Incoloy 800 series retain excellent mechanical properties, such as tensile strength, yield strength, and stiffness, across a broad range of temperatures. This guarantees dependable operation and enduring durability in demanding applications.
Easy to manufacture: These alloys can be produced in numerous forms, including stud bolts, using conventional manufacturing methods like hot forging and machining. This makes it possible to manufacture custom-sized stud bolts tailored to the requirements of specific applications.
Incoloy 800/800H/800HT Stud Bolts serve applications as varied as the industries that use them, led mainly by the aerospace, railway, construction and automotive industries along with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Petrochemical Industry: Stud bolts manufactured from Incoloy 800 series alloys are widely employed within the petrochemical sector, particularly in refineries and chemical processing facilities. They serve in reactors, heat exchangers, piping systems and more, where corrosive chemicals and elevated heat exposure frequently occur
Power applications: Incoloy 800 series stud bolts are utilized in electrical equipment, both conventional and nuclear, for uses such as boiler parts, steam turbines, exhaust systems and similar. These alloys are capable of enduring the high temperatures and pressures met in power generation.
Aerospace: For aerospace uses that demand lightweight, high-strength materials able to endure extreme conditions, Incoloy 800 series alloys serve for stud bolts and other fasteners found on airborne component engines, gas turbines and propulsion systems.
Heat treatment: The outstanding high-temperature characteristics of Incoloy 800 series alloys render them well-suited for heat treatment equipment like furnaces, annealing machines and heat exchangers. Stud bolts made from these alloys face elevated heat in such uses. They are also able to endure thermal cycling.
Chemical applications: Stud bolts fabricated from Incoloy 800 series alloys serve in a range of chemical applications, including the production of acids, alkalis and other corrosive substances. Their resistance to corrosion and oxidation makes them appropriate for the vessels, reactors, and piping systems of chemical plants.
Understand the difference: Incoloy 800, 800H, and 800HT are variants of the same alloy with minor differences in their composition and characteristics. Incoloy 800H contains more carbon, whereas 800HT offers superior creep-rupture performance. Identify the version that fits your needs best by considering factors like temperature, pressure, and environmental conditions.
Define application requirements: Specify the operating conditions, including temperature, pressure, corrosion resistance, and resistance to oxidation or sulfur-bearing atmospheres. Doing so will help you select the appropriate Incoloy stud bolts.
Refer to standards and specifications: To confirm alignment with performance and design requirements, consult industry standards and specifications like ASTM, ASME, and ANSI. These standards direct composition, devices, and design.
Consider corrosion resistance: Incoloy 800 series alloys are recognized for their outstanding corrosion resistance across many environments, including acidic and high-temperature settings. Review the particular corrosion challenges in your application and make sure the stud bolts you select deliver sufficient energy.
Check mechanical properties: Examine mechanical properties like tensile strength, yield strength, and stiffness to confirm the stud bolts can handle application loads and service conditions without failing.
